Questions
How big is the 2AAAHolder PCB?
It measures 47.8 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 2AAAHolder use?
53 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the 2AAAHolder KiCad files?
From the pa-pa/HMSensor repository on GitHub, at the commit this page was made from: the board is AddOns/2AAAHolder/2AAAHolder.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 2AAAHolder design in my own project?
Its repository states no licence, so its author keeps all rights: ask pa-pa before reusing the design.
